Why Science Teachers Are Struggling With Climate Change : NPR EdThe results of a new survey, published in the journal Science, suggest that many of America's middle and high school science teachers are misrepresenting climate change in their classrooms.

"They've all said: It's happening, and it's being caused by human activity. Add to that the fact that most of the published literature that you see in the big journals, like Science and Nature and Geophysical Research Letters, is all showing a consensus. It's overwhelming."

How overwhelming? According to this and this, roughly 95 percent of climate scientists believe global warming is happening and that humans are to blame.

That's why this new survey of some 1,500 middle and high school science teachers, representing all 50 states, is surprising. Roughly 3 in 4 say they talk about global warming in class, though typically only for an hour or two. But the study's lead author, Eric Plutzer of Penn State, says barely a majority are getting the science right.

"A little more than half are sending clear messages that human consumption of fossil fuels is the major cause of recent warming," Plutzer says.

What are the rest saying?

Well, roughly 30 percent tell students that humans are only partly to blame for climate change, along with natural causes. The problem with that, Plutzer says, is that it sends mixed messages, suggesting that the causes of climate change are still up for debate — when there is no debate among the vast majority of climate scientists. As for the rest ...

"About one in 10 [teachers] seem to be denying a human role altogether," while the remaining 5 percent don't talk about causes at all.

Why the disconnect between science teachers and climate science?

"Very few of our teachers had formal training while in college," Plutzer says, "and so the burden of learning the science falls to them."

Robert Clifton is in his third year teaching science at Rose Park Magnet Math & Science Middle School in Nashville. In college, he majored in biology but says he didn't get much climate science.

"I took an ecology class, but that was the extent of it," Clifton says. "As far as teaching it to the students, no, not a lot of it."

Molly Sloss is in her second year of Teach for America, teaching eighth grade science at Success Preparatory Academy in New Orleans. In college, she says, she took two good science courses, but that's it.

Luckily, Sloss says, "my mother was a middle school science teacher, so I pulled on her a lot."

We've been to school. We know how education works. Right? In fact, many aspects of learning — in homes, at schools, at work and elsewhere — are evolving rapidly, along with our understanding of learning. Join us as we explore how learning happens.
